1. A display device, comprising:
a data driver connected to a first data line and a second data line different from the first data line;
a first pixel circuit coupled to the first data line, the first pixel circuit including a first driving transistor, a first initialization transistor, a first anode initialization transistor, and a first light emitting diode emitting a first color, the first light emitting diode including a first anode and a first cathode, wherein; and
a second pixel circuit coupled to the second data line, the second pixel circuit including a second driving transistor, a second initialization transistor, a second anode initialization transistor, and a second light emitting diode emitting a second color different from the first color, the second light emitting diode including a second anode and a second cathode, wherein
a first anode initialization voltage is applied to the first anode through the first anode initialization transistor,
a second anode initialization voltage is applied to the second anode through the second anode initialization transistor, the second anode initialization voltage being different from the first anode initialization voltage, and
a cathode voltage commonly applied to the first cathode and the second cathode is smaller than the first anode initialization voltage.
